For those who haven't read Petshop of Horrors, Count D's Petshop is a place where one can find animals from the most ordinary housepets to savage predators to mystical beasts that should belong only in legends. Customers often find that their new pets change their lives more than they expect, fulfilling their dreams, or realizing their nightmares.

From Tokyopop:Kamishina Fuuto would like to think he's a normal boy, but he is the reincarnation of the High Priest of Darashaal, a tiny Asian country that has just celebrated the inauguration of... its new high priest. Clearly, only one of them is the true priest, and unfortunately for Fuuto, it is he. As the celestial guardians come to dispose of him, they discover that he is not, as their leader Naaga says, a fake. Fuuto just wants to be normal and live a normal life, but he is constantly drawn into trouble, as he has an extremely keen spiritual sense and the ability to soothe ghosts.

From Tokyopop: A smoke-filled alley in Chinatown harbors Count D's Pet Shop. The pets sold here aren't your everyday variety and the Count prides himself on selling Love and Dreams in the form of magical creatures that come with an exclusive contract. But buyers beware. If the contract is broken the Count cannot be held accountable for whatever may happen. A fascinating and macabre look into the very soul of human nature.
